The shop manual shows disconnecting rubber line that feeds into rail then putting in a metal T fitting then another rubber hose from T to rail and hooking the pressure gauge to that T fitting. That lets you measure but be very careful 50 PSI fuel can squirt out fast and start a big fire, burning jeep to ground, and killing you in the process

My 98 sport has one and the 04 rubi does not Also only the rubi has the damper on the rail It looks like the rails would be a straight swap so if you got a salvage yard one with a port it would probably swap in

I also have a fuel damper. I wonder if the PO had already done a swap? This pic is the back half of the FR. The damper is at the very front of pic.

Also now that you mention the 04 rubi, my owners manual says 2004 on the cover but the car is listed as 03 and says 06/03 on the door sticker? Also it has a Dana 44 rear (not sure about the front). Is it a mod or option I don't know? I know it was available from the dealer could it be some kind of rubi type package?
